Abstract

Radio receivers in the past used a single bandwidth data limiter filter. The result of this sin- gle bandwidth was a trade-off between falsing and sensitivity had to be made. Ifthe low pass data filter was narrow enough to provide good sensitivity it would band limit noise to appear data like to the baud rate detector. If the data filter was wide enough to pass enough noise that the baud rate detector did not false, the sensitivity during data decoding decreased. Selectable bandwidth decoding is a desir- able mode of operation for certain types of data decoding devices.
